for which Whale Rock serves as investment manager. Whale Rock, as those investment limited partnerships&rsquo;
investment manager, and Alexander Sacerdote, as managing member and owner of Whale Rock, may therefore
be deemed to beneficially own Securities owned by such investment limited partnerships for the purposes of Rule 13d-3 of the
Securities Exchange Act of 1934, as amended (the &ldquo;Act&rdquo;), insofar as they may be deemed to have the power to direct
the voting or disposition of those Securities.</P>

<P STYLE="Font: 9pt Arial, Helvetica, Sans-Serif; Text-Indent: 1.5em; Margin-Top: 6pt; Margin-Bottom: 6pt">Neither the filing of this Schedule nor any of its contents shall be deemed
to constitute an admission that Whale Rock or Alexander Sacerdote is, for any other purpose, the beneficial owner of any of
the Securities, and each of Whale Rock and Alexander Sacerdote disclaims beneficial ownership as to the Securities, except
to the extent of his or its pecuniary interests therein.</P>

13d-3 under the Act, it is also possible that the individual general partners, executive officers, and members of the foregoing
entities might be deemed the &ldquo;beneficial owners&rdquo; of some or all of the Securities insofar as they may be deemed
to share the power to direct the voting or disposition of the Securities. Neither the filing of this Schedule nor any of its
contents shall be deemed to constitute an admission that any of such individuals is, for any purpose, the beneficial owner
of any of the Securities, and such beneficial ownership is expressly disclaimed.</P>

<P STYLE="Font: 9pt Arial, Helvetica, Sans-Serif; Text-Indent: 1.5em; Margin-Top: 6pt; Margin-Bottom: 6pt">The calculation of percentage of beneficial ownership in Item 11 was derived from the Issuer&rsquo;s Quarterly Statement on
Form 10-Q  filed with the Securities and Exchange Commission on January 31, 2020, in which the Issuer stated that the number
of shares of Common Stock outstanding as of January 27, 2020 was 63,824,365.</P>
